Answer:
Power = 1920 Watts or 1.92 Kilowatts
Explanation:
Given the following data;
Resistance = 30 Ohms
Voltage = 240 Volts
To find power rating of the kettle;
Mathematically, the power consumption of an electric device is given by the formula;
Power = voltage²/resistance
Substituting into the formula, we have;
Power = 240²/30
Power = 57600/30
Power = 1920 Watts or 1.92 Kilowatts
At each step it should print out the move it makes and its performance score (e.g. S 0.2). Every 5 steps, it should print out a grid, with a "[ ]" on the square where the robot is now. Thus, with the above input, if the robot has done S U S L S, the output would be:
Answer:
The output would be S 0.2 U 0.2 S 0.2 U 0.2 L 0.2 S 0.2 [ ]
Explanation:
Given that at each step output prints for example S 0.2.
Also given after every 5 steps, it should print a grid "[ ]".
if robot has been given S U S L S, it prints output as
S 0.2 U 0.2 S 0.2 U 0.2 L 0.2 S 0.2 [ ]
Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. calcPyramidVolume() calls the given calcBaseArea() method in the calculation.
Answer:
The method in C++ is as follows:
double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){
double baseArea = calcBaseArea(baseLength, baseWidth);
double volume = baseArea * pyramidHeight;
return volume;
}
Explanation:
This defines the calcPyramidVolume method
double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){
This calls the calcBaseArea method to calculate the base area of the pyramid
double baseArea = calcBaseArea(baseLength, baseWidth);
This calculates the volume
double volume = baseArea * pyramidHeight;
This returns the volume
return volume;
}

g Why do database systems support concurrent execution of transactions, despite the extra effort needed to ensure that concurrent execution does not cause any problems
Answer:
Explanation:
To maintain data consistency and integrity in a large multi-user system, transactions are completed concurrently with the aid of concurrency management techniques.
The following are some of the benefits of concurrent transaction processing and execution versus serial transaction processing and/or execution:
Improved Resource Usage:
A transaction frequently combines both CPU and Input/output activities, resulting in better resource usage. Computers have the ability to run disks and CPUs in parallel. As a result, transactions can also be executed in parallel, with one employing the usage of the CPU and the other using the disk. As a result, resources are better used than in serial transaction processing and execution.
Improved throughput:
Running transactions in parallel has an immediate impact of increasing throughput since a greater number of transactions can be completed in the same period of time.
Lower/shorter waiting time:
Reduced wait time: When transactions are processed sequentially and serially, a short transaction is forced to wait for a longer transaction. Because transactions usually affect distinct portions of the database. As such, it's best if they happen at the same time i.e it is run concurrently.
The characteristics listed above are critical to a system's performance.
Thus, It is obvious that the benefits of concurrency exceed the extra programming work necessary to execute transactions concurrently. As a result, database systems must handle concurrent transactions despite the additional work necessary since it is worthwhile.

In which SDLC step does the company translate broad, user-oriented systems requirements into the detailed specifications used to create a fully developed system
Answer:
Physical design.
Explanation:
Systems development life cycle (SDLC) is a strategic process that involves determining the overall system architecture, which is typically comprised of hardware, end users, physical processing components, software, and the communication channel that will effectively and efficiently satisfy the essential requirements of the system.
The system inputs and outputs is typically designed along with a plan of how the system's features will be navigated.
Basically, system design is divided into two (2) categories and these includes;
I. Logical design.
II. Physical design.
Furthermore, the design of service systems involves the process of planning, creating infrastructure, building communication, organizing staffs and standardization of a system so as to improve its quality and business relationships between the service provider and its clients.
In the physical design of systems development life cycle (SDLC), broad, user-oriented systems requirements are obtained from end users by companies and then translated into the detailed specifications that would be used to create a fully developed system.

Write a program to sort the (name, age, score) tuples by descending order where name is string, age and score are numbers. The sort criteria is: 1: Sort based on name 2: Then sort based on age 3: Then sort by score The priority is that name < age < score. If the following tuples are given as input to the program: [('John', '20', '91'), ('Jason', '21', '85'), ('Jony', '17', '91'), ('Johny', '17', '93'), ('Tom', '19', '80')]\
Answer:
The program in Python is as follows:
from operator import itemgetter
m = int(input("Number of records: "))
print("Name, Age, Score")
my_list =[]
for i in range(m):
user_details = input()
my_list.append(tuple((user_details.split(","))))
my_list.sort(key = itemgetter(0, 1, 2))
print("Sorted: ", my_list)
Explanation:
This imports the operator function from itemgetter
from operator import itemgetter
This gets the number of records, m
m = int(input("Number of records: "))
This prints the format of input
print("Name, Age, Score")
This initializes the list of tuples
my_list =[]
This iterates through m
for i in range(m):
This gets the details of each person
user_details = input()
This appends the details to the tuple
my_list.append(tuple((user_details.split(","))))
This sorts the tuple
my_list.sort(key = itemgetter(0, 1, 2))
This prints the sorted tuple
print("Sorted: ", my_list)

In this lab, you complete a C++ program that swaps values stored in three int variables and determines maximum and minimum values. The C++ file provided for this lab contains the necessary variable declarations, as well as the input and output statements. You want to end up with the smallest value stored in the variable named first and the largest value stored in the variable named third. You need to write the statements that compare the values and swap them if appropriate. Comments included in the code tell you where to write your statements.InstructionsEnsure the Swap.cpp file is open in your editor.Write the statements that test the first two integers, and swap them if necessary.Write the statements that test the second and third integer, and swap them if necessary.Write the statements that test the first and second integers again, and swap them if necessary.Execute the program by clicking the "Run Code" button at the bottom of the screen using the following sets of input values.101 22 -23630 1500 921 2 2Provided code:// Swap.cpp - This program determines the minimum and maximum of three values input by// the user and performs necessary swaps.// Input: Three int values.// Output: The numbers in numerical order.#include using namespace std;int main(){ // Declare variables int first = 0; // First number int second = 0; // Second number int third = 0; // Third number int temp; // Used to swap numbers const string SENTINEL = "done"; // Named constant for sentinel value string repeat; bool notDone = true; //loop control // Get user input cout << "Enter first number: "; cin >> first; cout << "Enter second number: "; cin >> second; cout << "Enter third number: "; cin >> third; while(notDone == true){ // Test to see if the first number is greater than the second number // Test to see if the second number is greater than the third number // Test to see if the first number is greater than the second number again // Print numbers in numerical order cout << "Smallest: " << first << endl; cout << "Next smallest: " << second << endl; cout << "Largest: " << third << endl; cout << "Enter any letter to continue or done to quit: "; cin >> repeat; if (repeat == SENTINEL){ notDone = false; } else { cout << "Enter first number: "; cin >> first; cout << "Enter second number: "; cin >> second; cout << "Enter third number: "; cin >> third; } return 0;} // End of main function

{
int temp = first;//defining temp to hold first value
first = second;//holding second value in first variable
second = temp;//holding temp value in second variable
}
if(second > third)//use if to compare second and third value
{
int temp = second;//defining temp to hold second value
second = third;//holding second value in third variable
third = temp;//holding temp value in third variable
}
cout << "Smallest: " << first << endl;//print smallest value
cout << "Next smallest: " << second << endl;//print Next smallest value
cout << "Largest: " << third << endl;////print Largest value
cout << "Enter any letter to continue or done to quit: ";//print message
